CHEESE-CUTTER.

Specification of Letters Patent.

Patented Aug. 28, 1906.

tate of ones being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

Figure 1 is a plan view of the invention.

Fig. 2 is a sectional view on line 2 2 of Fig. 3

Fig. 3 is a detail view of the vertical arc scalebar. Fig. 4 is a detail view of the ratchet-, box. Fig. 5 is a detail view of the brake or, stop lever. Fig. 6 is a side view of the invention.

The invention relates to computing cheesecutters; and it consists in the novel construction and combinations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter a designates the base, having a central bearing 1) for the pivotpin 0 of the rotary wheel-frame d, which is milled on its circumference deeply to engage the pawls e of the radial lever This lever is also pivoted on the pivot-pin 0, being provided at its inner end To the board, on which the cheese is designed to be placed and pro erly centered.

At the peri liery of the base opposite the outer end of t e radial lever and spanning its path of movement is secured to the base a vertical arc-bar g, the upper surface of which is provided with graduatiommarks, representing total values of cheeses. This areher is provided near one end with a stop-lug h, which marks the point of beginning for a movement of the vertically-operating handle is, which is pivoted in a bearing of the base centrally between the arms of the arc-bar and is provided on its inner end with a pinion m.

The radial lever f is provided with a boxing it above this pinion, said boxing containing the pawls e and their springs s and having upon its under side the rack-teeth t in en.-

sufliciently gagenient with the pinion m. U on the areher is located the limiting or in icator strap w, which is adjustable to position in accor anee with the value of the cheese upon the board of the cutter.

In the arc-bar is a longitudinal recess 1*, having a slot p, and in the recess is located a coilspring 9, one end of which is attached to the arc-bar near the stop-1ug h or point of beginning and the other end of which is attached to the adjustable stop w. This coilspring is provided with four indicators 11' at even distances apart, and from the stop-lug h and from the adjustable stop w, said indicators projecting through the slot 1). These indicators serve to mark, respectively, the worth of one cent, of two cents, of three cents, and of four cents. They are automatically adjustable proportionally to the total value of the cheese as indicated on the arc-bar scale, owing to their connection with the spring.

When the limitin stop is set for a certain ortion of cheeset at is to say, for instance, ve cents worthby moving the handle it from its starting position to the limitingstop, then back to starting position, and then forward. again to the third indicator '0, eight cents worth will be measured, for the action of the cu.ttingknife, as the pawls act to rotate the wheel-frame d in one direction only.

In a similar manner seven or nine cents wortlrcan be measured off, always with the advantage of avoiding any half-cent com plications.

To the pawl-boxing u at one end is connected a spring 2, the other end of which is connected to the base. This spring is designed to hold the pawls to their work in an exact manner, taking up the play at the bearings, notwithstanding there may be some wear of the operating parts.

The knife-handle 3 is pivoted to an arm of the frame and is provided with a vertical slot hearing or recess 4 in which the knife-blade is seated, being held there by setscrews 6. In order to provide against moving the 0 erating-handle before raising the knife, a ock is rovided to be operated by the knife in the foiiowing manner: The base is provided with a brake or sto lever 7, having an arm projecting above t e board or table on which the cheese is laced and at the back of said board in t e path of the point portion 8 of the knife. When the knife is brought down in cutting off a slice of cheese, it engages the stop-lever, which in turn engages the wheelframe, holding it in locked position until the knife is raised, when said wheel-frame is at liberty to be moved by the operating-handle.

The total-value scale, herein shown on the scale-bar g, is mounted inversely with relation to the movement of the actuating handle-lever A: that is, in the direction of the forward movement of said lever said scale diminishes from a higher numeral to smaller numerals, so that the larger numeral is nearer the fixed stop 71. Furthermore, the distance between the graduations increases gradually in the direction of the forward movement of said lever and in a direction away from said fixed stop. Also the means actuated by the handle-lever k for moving the cheese-carrier is so arranged that at each movement of said handle-lever and carrier the handle-lever will move through a greater are than the carrier. This feature of the arrangement, in combination with the inversely-arranged total-value graduation-scale, as set forth, constitutes a very important and practically valuable improvement in computing cheese-cutters. It furnishes a device wherein the total selling price only is necessary to be known by the operator for setting his ad'ustable stop and then the handle-lever will ave a uniform throw or movement through a relatively considerable are, so that the graduations and numer als of the scale may be far enough apart to be readily visible and to render convenient the adjustment of theadjustable stop as Well as artial operations of the actuating handleever It. Therefore with this device portions of uniform value may be cut from cheeses of varying weights and values at each throw of the lever, and after the device has been set for a certain cheese each throw of the lever, even in the dark, will move the cheese so that there will be cut therefrom portions of a certain unit of value. While the part marked 10 herein is called an operating-handle, it is mechanically a lever for actuating the cheese-carrier.

Having described the invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a cheese-cutter, the combination with the base and the wheel-frame centrally pivoted thereto, of the ivoted radial arm, the clutch device and rac teeth located thereon, the arched scale-bar, the operating handlelever, its journal and the pinion on said 'ournal engaging said rack-teeth, substantia ly as specified.
